Access to TV greenrooms is usually restricted — but viewers are getting a backstage pass to NBC’s “Late Night With Seth Meyers” in the May issue of Architectural Digest.

When Meyers wanted to give the show’s dressing rooms and greenroom at 30 Rockefeller Plaza a style worthy of its A-list guests, he decided to make it a family affair, enlisting sister-in-law Ariel Ashe of Manhattan design firm Ashe + Leandro to redo the space. (Abstract paintings by his mother-in-law also hang in a dressing room.)

“I myself do not have a smart visual sense, but I am smart enough to turn to people who do,” Meyers — who married Ashe’s younger sister, Alexi, last September — tells the magazine.

Updating his personal suite, four dressing rooms for the show’s band members and celebrity guests, the greenroom and kitchen required pouring new concrete floors, removing drop ceilings and replacing the building’s fluorescent lights with sconces and ceiling lamps.
